Viwinco’s patented Tilt-n-Lock system  allows users to open, close, and tilt the window with press of the latch, requiring only one hand to operate. The innovation eliminates the traditional tilt latches on both ends of the sash, which require two hands to active and often collect dust and dirt. Tilt-n-Lock is standard on Viwinco’s Cambridge replacement windows and OceanView impact-resistant windows, and as an upgrade on its Viwinco S-Series new construction windows.
Editors’ Comments: This is a great universal design improvement to the traditional tilt window. The lock level is spring-loaded, making operation a snap.
